A look at some memorable moments in Seahawks history that occurred on May 3:

1977: The Seahawks trade the second pick in the NFL Draft to the Cowboys, who select running back Tony Dorsett. In exchange, the Seahawks get the Cowboys’ first-round pick, which they used to select offensive lineman Steve August; and three second-round picks – which became offensive lineman Tom Lynch and linebacker Terry Beeson. Beeson would lead the team in tackles for three consecutive seasons (1977-79), including a still-franchise record 153 in 1978. August started 90 games from 1977-84.

1978: Cornerback Keith Simpson is selected in the first round of the NFL Draft, and linebacker Keith Butler is added in the second round. Simpson would start 70 games in eight seasons with the team, retuning three of his 19 interceptions for touchdowns; while Butler was the franchise’s all-time leading tackler by the time he left after the 1987 season with 813 – a mark that would be broken by Eugene Robinson (984).

1979: Manu Tuiasosopo is selected in the first round of the NFL Draft. The defensive tackle from UCLA would lead the team in sacks (eight) as a rookie and produced a career-high 94 tackles in 1980. He started 64 games in five seasons.
